We ended up having to copy the files in the original database to a new database. We were then able to insert our new records. All has been well, until yesterday, when the same durn thing happened again. Rather than overwriting some records, however, it just simply was not allowing an insert at all. We copied the data to a new test area database, and inserting works there. Running DBCC CHECKDB against the problem area gives us no error messages.

Suggestions?
